Effect of Core Structure on Cut Resistance of Covered Yarn Fabrics

Abstract

Anti-cut fabric is a type of personal safety protection material that can protect the human body from injuries caused by sharp objects, such as knives. It not only holds significant application value in military and police security sectors but is also widely used in civilian fields. Therefore, developing anti-cut fabrics that are both lightweight and possess excellent protective performance is of great importance in addressing the potential dangers posed by sharp tools. This study utilized ultrahigh molecular weight polyethylene (UHMWPE), aramid 1414 (Kevlar), stainless steel filament (SSF), and polyamide (PA) as raw materials to design and fabricate eight types of yarns and their plain–woven cut-resistant fabrics by modifying core yarn structures. Through a series of experiments, the cut-resistant properties of fabrics with different core yarn structures were systematically investigated, followed by comprehensive evaluations and theoretical analyses. Testing results revealed that the characteristic cutting forces of B_P, B_K, C_P, and C_K specimens were 1535.78 gf, 1687.61 gf, 1731.56 gf, and 1902.54 gf, respectively, meeting the A4 grade requirements of the ANSI/ISEA 105-2016 standard. In contrast, the A_P, A_K, D_P, and D_K specimens exhibited characteristic cutting forces of 1460.20 gf, 1494.56 gf, 962.63 gf, and 1347.57 gf, complying with the A3 grade specifications. The findings indicate that twisting a single core yarn component can effectively enhance the fabric’s cut resistance. This research provides both theoretical foundations and practical guidance for the design and development of high-performance cut-resistant textiles.
